Set a default MMIO region with a single SmePMP entry, which allows us
to save entries for M-mode only devices. The default entry has M-/S-mode
shared permission, so system-level resource protection, such as RISC-V
World extension and WorldGuard checker, will be introduced to protect
M-mode only region access from lower privilege modes.
